MONTREAL, CANADA.

RIFLE-SIGHT.

SPECIFICATION forming part of Letters Patent No.751,200, dated February 2, 1904. Application filed January 13, 1902. Serial No. 89,613. (No model.)

To all whom it may concern:

Be it known that I, JOHN TAYLOR PEDDIE,

insurance broker, of the city of Montreal, in'

the district of Montreal and Province of Quebec, Canada, have invented certain new and useful Improvements in Bille-Sights; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to laterally-adjustable sights whereby the deflection due to wind can be compensated for and the proper elevation n given relatively to the range at which shooting is to be done, and has for its object to so improve the construction of the same that a greater degree of lateral movement of the movable sight-carrying member, coupled with absolute steadiness thereof, is obtainable, as well as a strengthening of the operating parts, a more convenient operation, and the possibility of easily removing any accumulation of dust, &c. ,likely to interfere with the operation.

The main feature of the invention may be said, briefly, to consist in the particular construction of the laterally-movable sight-carrying member and its connection with the i-Xed base, which construction and connection may be briey described as follows: The base secured to the gun-barrel is formed to present v a central transverse slot and a pair of transadjustable sight-carrying member comprisesV a pair of slides fitting said guideways and connected by a bridge-piece extending from the top of eachslide over and above the central or interveningsection of the base and being of a width less than that of theslides and of the base, the movable sight-carrying member having a projection on its under side which enters the slot in the base and presents-a screwthreaded aperture to receive the operating thumb-wheel `of convenient size.

Other more specic combinations of parts are hereinafter' described, and pointed out in the claims. f

For full comprehension of my invention reference must bel had to the accompanying drawings, forming a part of this specication, in which like symbols indicate the same parts, and wherein,-

Figure 1 is a perspective view of a portion of a rifle provided with my improved sight. Fig. Q'is a plan View of the sight enlarged and partly in section with the sight-frame in its upright position. Fig. 3 is a similar View with the sight-frame closed down. Fig. 4 is a longitudinal vertical section on line 4 4:, Fig. 3.

My improved sight comprises a base secured rigidly upon the barrel and having a pair of transverse dovetail guideways c and d, an opening or 'slot e between said guideways, and boringsf in line with one another through .portions of the base at the ends of said slot,

while one end of said base is beveled, as at g.

The laterally adjustable sight carrying member comprises a pair of dovetail slides h and t', which are adapted to t and slide in the .respectivevguideways c and d and are conpiece also has a projection a on its under side to enter said slot. The bridge-piece is of less width than the dovetail slides in order that a clearance on each side may be left to secure a greater lateral adjustment than has hitherto been obtainable in sights of this type, and by forming the movable sight-carrying member of the two dovetail guides and bridge-piece a central vertical clearance is obtainable, which allows a substantial portion of the base to be `used as bearings for the operating-screw and in a recess formed by an opening q through said slide z', in which the free end of the bowspring is bent to bear upon the under side of said square lug. The usual cross-bar 1, with a V-notch midway between the ends of the side thereof, is carried slidably upon the graduated sides of the open frame, and I have also provided graduations upon the bowspring which follows the inclined upper side of the bridge-piece, whereby the adjustment of the cross-bar fr to regulate the elevation of the arm for distances under live hundred yards may be determined.

The side of the dovetail slide z' adjacent to the beveled end of the base is also beveled correspondingly, and the beveled end of the base has graduations thereon representing live degrees each, while the beveled side of the slide has graduations representing units. The movable sight-carrying member comprising the dovetail slides and connecting bridge-piece is adjustable laterally by a transverse screw Z, rotatably mounted in the borings fin the base and threaded through a tapped boring in the projection a from the under side of the bridgepiece. In order to enable an adjustment of units or lives, I mark the edge of the slide with live subdivisions to each four upon the registering edge of the base, counting from a central zero, each of the upper subdivisions representing a single degree, while each of the lower subdivisions represents live degrees.

That I claim is as follows:

1. In a laterally-adjustable gun-sight, the combination with a base secured to the gunbarrel and presenting' a pair of transverse dovetail guideways, of a laterally-adjustable sightcarrying member comprising a pair of slides litting said guideways, and a longitudinal bridge-piece connecting said slides and being of a width less than that of the base, the said sightcarrying member carrying a hinged sight-leaf and the said bridge-piece being graduated and adapted to support said sightleaf in dierent angular positions predetermined by the graduation upon the bridgepiece, the sight-carrying' member with the parts carried thereby being collectively adjustable laterally of the gun, substantially as described and for the purpose set forth.

2. In a laterally-adjustable gun-sight the 'combination with a base secured to the gunvbridge-piece, a slider upon said frame and movable longitudinally thereof, and means for adjusting said sight carrying member, substantially as described and for the purpose set forth.

3. In a laterally-adjustable gun-sight, the combination with a base secured to the gunbarrel near the breech, and presenting a central transverse slot and a pair of transverse dovetail guideways, of a laterally-adjustable sight-carrying member comprising a pair of slides litting said guideways, and a longitudinal bridge-piece connecting said slides, presenting a projection on its under side entering said slot and being of a width less than that of the base; a sight carried by said member, and means connected with said projection and with the base for adjusting the member, substantially as described.

4. In a laterally-adjustable gun-sight the combination with a base secured to the gunbarrel presenting a central transverse slot and a pair of transverse dovetail guideways and having the end nearest the breech beveled and graduated, of a laterally-adjustable sight-carrying member comprising a pair of slides fitting said guideways and a longitudinal bridgepiece connecting said slides presenting a projection on its under side entering said slot and being of a width less than that of the base, the slide nearest the breech being beveled to correspond with the bevel of the end of the base and being graduated; a sight carried by said. member, and means connected with said projection and with the base, for adjusting' the member, substantially as described.

5. In a laterally-adjustable gun-sight the combination with a base secured to the gunbarrel near the breech, presenting a central transverse slot and a pair of transverse dovetail guideways and having the end nearest the breech beveled and graduated, of a laterallyadjustable sight-carrying member comprising a pair of slides litting said guideways, and a graduated longitudinal bridge-piece extending from the top of said slides across the central portion of the base and being of a width less than that of the base, the slide nearest the breech being Vbeveled to correspondl with the bevel of the end of the base and being graduated, a sight-leaf hinged to the sight-carrying member, a slider on the sight-leaf adapted to ride on said bridge-piece, and means for adjusting said sight-carrying member, substantially as described.

6. In an adjustable gun-sight the combination with a base secured to the gun-barrel presenting a central transverse slot and-a pair of transverse dovetail guideways and having the end nearest the breech beveled and graduated to indicate lives, of a laterally-adjustable sight-carrying member comprising a pair of slides litting said guideways, and a graduated longitudinal bridge-piece extending from the top of said slides across the central portion of the base, and being of a width less than that of the base, the slide nearest the breech being IOO IIO
